Here's a link to Thomas Thomson House.
http://www.nas.gov.uk/about/map2.aspNo offence to anyone who lives in Sighthill, but it's a bit of a concrete jungle, miles from the city centre. The only time my wife and I ever go there is to take bulky rubbish items to the recycling tip, which is sensitively positioned next to Edinburgh College. Lucky students. What an environment to study in.
Years ago when I often visited the former Scottish Record Office next-door to the GRO, I occasionally requested a valuation roll and was told they were kept up at Sighthill and I would have to wait 24 hours. I didn't mind, as everything else I needed to look at, e.g. kirk-session and heritors' records, were kept in the SRO and only took minutes to arrive.
The prevailing wisdom in Edinburgh these days is, if it's a lovely old listed building, turn it into a luxury hotel. That was the fate of the Scotsman building at North Bridge, and the journos were decanted to a new building down near the Scottish parliament. Now that building has been sold too, to some games company, I believe, and the Scotchman has decamped again, to an anonymous office building at Orchard Brae, facing the Dean cemetery, which should concentrate their minds.
A luxury hotel is also the latest fate proposed for the iconic former Royal High School building on Calton Hill, which was once touted as the home of the parliament. Plans and mock-ups have appeared in the local press. I hope something positive is done with it soon as it is apparently in a dire state inside after years of neglect.
